Reliable socket transmission discussion.
Reliable socket transmission
Major applications are transmitted using some form of data.In some cases, data transmission is maintained at computing device
The local of storage device and/or.In other cases, data transmission expansion be more than computing device reach external computing device and/
Or storage location.Either this number can be assisted in the inside of computing device or outside, various types of communication links
According to transmission.As an example, Berkeley socket utilizes the function tune that each endpoint is implemented as involved in communication link
Standardization library.When first end point is wished with the second endpoint communication, first end point can be called by the offer of standardization library
API.Assuming that each endpoint implements the interface and/or agreement that each endpoint understands, it is then able to establish communication link.
Different applications may expect the different configurations of associated communication link.For example, the first application can be around logical
The data for crossing first set of words are transmitted to design, and first set of words is configured to hinder the execution of application simultaneously in response to request etc.
Wait returned data.Second application may be sent around the data transmission scheme by the second socket, the second socket for number
According to request, but wait response when do not hinder application execution.Instead second socket may be configured to week
Phase property ground poll returned data, but extra process is carried out between poll.Then, different application may expect to be based on attempting to reality
The socket and/or communication link for what showing different input/output (I/O) model is utilized to configure.
Some computing devices have while running the ability of several applications.Furthermore, it is possible to configure it is some or all of application with
It establishes and/or transmits data using communication link.Although can configure computing device with and meanwhile utilize (multiple) communication link
Several applications are run, but computing device can have and transmit less hardware than request application execution data.In these cases,
Computing device can have additional IO management and/or ability, and to help to make, data are transmitted and/or hardware resource management is more effective
Rate.For example, I/O Manager functionality can be implemented in some computing devices, for example, being answered by operating system component, one or more
With and/or I/O subsystem, cooperate with IO completing port, as passing through the shared hardware management data between multiple applications
A kind of method of transmission, as further discussed below.
Other than facilitating data to transmit, some communication links can have additional attribute.For example, some participants
And/or endpoint can request that and authenticate associated communication link before allowing to carry out data transmission by communication link.But,
Identifying procedure usually will increase additional agreement and/or handshake procedure so that using communication link application otherwise do not know this
A little or application designer is not intended to be coupled in application to make great efforts to keep application more general.In order to assist these applications,
The operating system code and/or general-purpose library that some embodiments are called indirectly to application increase communication link identifying procedure.Then this
A little communication links can be initialised, connect and/or be authenticated using operating system code and/or general-purpose library, and next will
It is transmitted to recipient using for further use.
Each embodiment will transmit associated communication link initialization between the participant in communication link with data
Connection status.In some cases, communication link and the first IO completing port are effectively matched to be able to carry out data transmission.One
A little embodiments reinitialize into holding participant by communication link and the first IO completing port disassociation and by communication link
Between connection status original state.In some cases, the communication link reinitialized can be transmitted for new opplication
It uses.For example, it is contemplated that Fig. 3, it illustrates the exemplary environments 300 for describing socket communication link and the pairing of IO completing port.
Include in environment 300 is application 108a, socket preprocessing module 110 and the I/O Manager module 112 of Fig. 1.
As described above, representing the application of any appropriate type using 108a, such as operating system component, user's application, library component etc..For
For the sake of simplicity, representing the logical groups for being configured to execute the executable code of certain function used here as term " application ".One
In a little situations, this executable code group may imply being capable of independently operated " independence " application.Alternately or additionally property, this
Kind code-group, which can imply, can call library and/or operation system function.Then, " application " is intended to imply that is taken various forms visits
The wide scope of asking property is functional.It further include showing the socket layer for the multiple sockets for including in environment 300 in environment 300
302, and additionally illustrate the IO completing port 304 of multiple IO completing ports.In this example, using 108a and socket
Preprocessing module 110 communicates, as a kind of its mode is initialized and/or accessed to communication link.For example, in some realities
It applies in example, as described above, calling API associated with socket processing module 110 using 108a.Herein, socket is located in advance
Reason module 110 establishes the socket 306 for being included in socket layer 302.The gray shade of socket 306 is for indicating socket
306 are initialised, and are connected to endpoint and/or associated participant, and the individual IO completing port with IO completing port 304
308 pairings.By similar fashion, IO completing port 308 includes gray shade, to indicate that it is matched with socket 306.Further
It is to be noted, that in this example, the individual IO completing port 310 being also included in IO completing port 304 is not connect with socket 306
And/or pairing, such case is indicated followed by no gray shade.
Socket can be bound into IO completing port by any appropriate ways.For example, in some embodiments, socket
Word can be represented by socket handle.Socket handle can be especially used as to management socket and realize the program to socket
Property access a kind of mode.In some cases, the associated function of socket handle can be called to pass through phase
Associated socket realizes data transmission.Socket handle can be used as and be directed toward associated set by alternately or additionally property
Connect the identifier and/or pointer of word.In order to which IO completing port is bound to socket, some embodiments transmit socket handle
To IO completing port.And IO completing port can safeguard socket handle list, represent IO completing port be responsible for each of
Socket and/or socket handle can safeguard the pointer for being directed toward IO completing port.Alternately or additionally property, can will be socketed
Words and expressions handle and IO completing port pass to I/O Manager module 112 together.By the way that socket is bound to IO completing port, IO is complete
The some functions transmitted and taken the circumstances into consideration for socket monitoring data for socket unloading task are undertaken at port.For example,
In some embodiments, IO completing port can receive the notice of input data, and can realize data by any appropriate ways
Retrieval, such as to awaiting tasks unloading data retrieval, notify the associated application of input data.
In some embodiments, by socket and/or socket handle be associated with IO completing port be configured with socket with
Utilize specific I/O model.For example, in this I/O model, when socket handle is associated with completing port, operating system mark
The associated with object of socket handle is remembered, so that all associated with completing port using any IO in future that handle is sent.No
It crosses, it is recognized that socket can be associated with without using other I/O models of IO completing port.For example, some I/O models are anti-
And use API associated with Berkley socket carries out event notice.There may come a time when it is beneficial using IO completing port.
For example, data transmission can be made more efficiently by allowing socket to be tied to associated IO completing port.For example, using IO
Completing port model can allow for the caller of socket to obtain the readjustment of system thread pool when can be used on socket in data
Function.But, it is more special to may also cause socket/socket handle in this way, and versatility is more for other application
It is low.For example, it is contemplated that situation as described above is similar to, wherein routing communication link by the agency of request certification.It is appropriate to realize
A kind of mode of certification may include allowing using understanding identifying procedure.But, as described above, will may undesirably answer in this way
With being coupled to agency and/or communication link.
In some embodiments, identifying procedure and application can be decoupled.It as described above and as further discussed below, can
To carry out initialization and/or among the participants connection communication link to communication link.This may include execute identifying procedure and/
Or by communication link with and the associated first IO completing port of the first I/O model it is associated.Complete initialization and/or certification
After process, communication link can be reset and/or reinitialize into original state by some embodiments, while keep associated
Connection status between participant.Some embodiments are then by the communication link for resetting and/or reinitializing to second
Using and/or the 2nd IO completing port.Alternately or additionally property, the communication link that can will reset and/or reinitialize
Being reset to enables communication link state associated at least the 2nd I/O model.
Consider Fig. 4, it illustrates another embodiments of the exemplary environment 300 of previously described Fig. 3.As previously mentioned,
Through establishing communication link via socket 306 and associated IO completing port 308.In some cases, it initializes and/or builds
Vertical may include the identifying procedure for executing any appropriate type associated with link.This can be managed by any appropriate ways
The identifying procedure of seed type.In some embodiments, these processes can be managed via socket processing module 110.Alternatively
Or additionally, it can be at least partially based on using the first I/O model and execute initialization and/or foundation.Herein,
It establishes after communication link, has made decision with by socket 306 and 308 disassociation of IO completing port, while keeping extremely
Connection between few some participants.The association of socket 306 and IO completing port 308 can be realized by any appropriate ways
It releases.It in some cases, can the removal socket associated with socket 306 from the list that IO completing port 308 manages
Words and expressions handle.Alternately or additionally property, can by communication link associated with the first I/O model that IO completing port 308 uses
Any setting resetting and/or be initialised to default conditions.
In order to further illustrate, consider that application is likely to be coupled to the example above of identifying procedure.It is substituted in coupling within application
Identifying procedure is closed, some embodiment configuration applications are to request the communication for having passed through identifying procedure and/or process is established
Link.In this way more particularly to will apply from including that any knowledge relevant to certification communication link decouples.Herein, socket is pre-
Processing module 110 is communicated to I/O Manager module 112, it is desirable to be reset and/or be reinitialized socket 306, while keep it
Connection status.In response to (multiple) communications, socket 306 is reset and/or is reinitialized to generally by I/O Manager module 112
Change state, such as any IO completing port association is removed, the label etc. of resetting driving notice.Then, generalized state can weigh
Set any suitable parameter associated with the first I/O model.Alternately or additionally property, to reinitialize communication link can solve
Except with any pairing of existing I/O port and/or be associated with, such as the association between socket 306 and IO completing port 308.At this
In, using the mixed and disorderly pattern masking socket 306 of grey to indicate connection status, and IO completing port 308 is no longer shielded, with table
Show that it is no longer associated with socket 306.Then, Fig. 4 shows socket 306 and connect with IO completing port 308, but no longer with its
It is associated.
Continue, Fig. 5 shows another embodiment of the exemplary environment 300 of previously described Fig. 3.In Fig. 5, environment
300 include the second application, here shown as 108b is applied, is distinguished with the application 108a with Fig. 3 and 4.As described above, using
108b represents application of any appropriate type, such as application, the library component of operating system component, user's driving etc..In this model
In example, the socket for connecting and authenticating is requested from socket preprocessing module 110 using 108b.And socket preprocessing module
110 again to application 108b transmission and/or reallocation socket 306 for using.As a part of this reallocation, sometimes may be used
Socket 306 and new IO completing port to be matched.For example, using 108b may be configured to using with for connect and/
Or different the second I/O model of the first I/O model of certification socket 306.In addition, the second I/O model can be completed from different IO
Port, such as IO completing port 308 are associated.Due to socket 306 be reinitialized into it is more neutral but connection
State, so using 108b socket 306 can be configured according to the second I/O model.As a part of this process, can incite somebody to action
Socket 306 and IO completing port 310 match, their association is both indicated with gray shade.Due to socket 306
